Given numbers are 778, 378, 772, 839

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(778, 378) = 147042

GCD(778, 378) = ( 778 x 378 ) / 147042

= 778 / 378

= 778

Step2:

LCM(2, 772) = 772

GCD(2, 772) = ( 2 x 772 ) / 772

= 2 / 772

= 2

Step3:

LCM(2, 839) = 1678

GCD(2, 839) = ( 2 x 839 ) / 1678

= 2 / 839

= 2

So, Greatest Common Divisor of 778, 378, 772, 839 is 1
